by Stephen Warren 28 Aug '12

[alsa-devel] [PATCH] ALSA: hda: Make core jack usage unconditional
by Mark Brown 28 Aug '12

28 Aug '12

Currently the HDA drivers have a Kconfig variable SND_HDA_INPUT_JACK which disables jack reporting via the ALSA core jack API. This is bad since (modulo the current problems with the HDA-specific reporting API) it means that all reporting mechanisms will get disabled, not just input. It's also not good that this is open coded in an individual driver - if it's useful to have this control it's going to be equally useful for any driver with jack detection support so should be handled in the core.

[alsa-devel] [RFC] ASoC: snd_soc_jack for HDMI audio: does it make sense?
by Ricardo Neri 27 Aug '12

27 Aug '12

Hello! I have been working on prototypes for the ASoC OMAP HDMI audio driver to propagate events from the HDMI output (e.g., display getting enabled/disabled/suspended). This for the users of the driver to react to such events. For instance, if the display is disabled or disconected, audio could be stopped, rerouted or whatever other decision the user makes. This is needed because, if, for instance, the HDMI IP goes off, audio will stall and the audio users will only see a "playback write error (DMA or IRQ trouble?)" In my prototypes I have used snd_soc_jack for this purpose and I have some questions: *I see snd_soc_jack is used mostly for headsets and microphones with actual external mechanical connections. Strictly, in my case I propagate events originated by the OMAP display driver (changes in the power state), and not from external events. Some of these events are generated from an actual HDMI cable connection/disconnection, though. *Maybe the event should be propagated by omapdss/omapdrm/drm and the entity in charge of the audio policy should listen those events instead. *I do see SND_JACK_VIDEOOUT and SND_JACK_AVOUT types so maybe it is feasible for an audio driver to report events from an AV output. I was wondering about how much sense does it make to you guys use a snd_soc_jack in this case? Thanks in advance for your comments! Ricardo

It takes me a long time to build > kernels locally, and I wasn't sure how to do a scratch build on koji without > committing stuff remotely. Actually you don't have to rebuild the whole kernel at all just for debugging this usb-audio bug. The workflow below is what I do often for debugging a driver problem on a distro kernel. 1. Prepare the compile-ready kernel source tree corresponding to your running kernel. This may depend on distro; in the case of SUSE, kernel-default-devel.rpm must be installed for kernel-default.rpm, for example. 2. Copy sound/usb subdirectory of the kernel source tree locally anywhere else, say, $HOME/usb. It can be a normal user directory. 3. Apply the patch to that local directory. 4. Build modules as a normal user like % make -C /lib/modules/$(uname -r)/build M=$HOME/usb modules 5. Make an extra update directory in the module directory once, e.g. # mkdir /lib/modules/$(uname -r)/updates 6. Copy *.ko files to there # cp $HOME/usb/*.ko /lib/modules/$(uname -r)/updates 7. Run depmod once # /sbin/depmod -a 8. Reload snd-usb-audio module. If you want to take back to the original module, just remove updates module directory and run depmod again. Pretty convenient, eh? HTH, Takashi
